No, the youtubers don't speak for all gamers.

However, their videos, and their audience members' responses to their videos, proves that a huge preponderance of gamers - meaning literally hundreds of thousands to millions of people - know both that:

a) GOG flagrantly outright lied to them by saying they banned Devotion because "many gamers" told them to

b) GOG bent the knee to the CCP and banned the game solely in order to appease them, which is a fact that GOG is too cowardly to admit, hence their "many gamers" lie

And those, we who are the real many gamers who actually exist (unlike lying GOG's fictitious ones who they just fabricated out of thin air as a scapegoat cover-up for their bending of the knee to the CCP), they are boycotting GOG in droves as a consequence.

They may not raise a huge fuss about it here on the GOG forums (where it seems GOG apologists are now starting to out-number honest gamers who call GOG out on their diabolical crap, hence the mass down-rating of anyone who speaks honestly about this matter), but that silent majority do vote with their wallets, and GOG is financially suffering for that as a consequence, and will continue to do so until if & when they ever decide to "man up" and make things right in regards to this debacle.

By the way, "firstpastthepost," to use your own premise again: do the "many gamers" that GOG alleges caused them to ban the game...do they speak for all gamers? And if not, then why do they get a special privilege to dictate to GOG what games must be banned? Who made them gods or kings over all other gamers? How come normal actual GOG customers don't have that same power to ban games they don't like off of GOG?
